This is a bit off the question you asked, but you might consider making a NRRD header file, which is a simple text file that provides the information you normally have to enter by hand in the raw file reader (http://teem.sourceforge.net/nrrd/). I like using NRRD headers so that I don't have to continually enter this information (that I tend to forget) every time I load the file, and that don't have that gotcha with the dimensions/extent indexing that Cory describes.
As an example, a NRRD header file for your file could be called snail_partial_348x250x348_float32.nhdr and contain the following: NRRD0004 dimension: 3 sizes: 348 250 348 spacings: 1 1 1 endian: little type: float (or `unsigned char' for the other version) encoding: raw data file: snail_partial_348x250x348_float32.raw -Ken On 11/6/12 7:00 AM, "Cory Quammen" <[email protected]> wrote: >Hi Robert, > >On Tue, Nov 6, 2012 at 8:37 AM, <[email protected]> wrote: >> Dear List >> >> I hope it's some silly 'newbie' issue, but I find myself completely >>unable to read a raw binary data file using the raw binary data file >>reader.
